Answer:

1. B = 30

2. G = 10

3. R = 10

4. M = 3

5. K = 4

6. C = 27

Step-by-step explanation:

1. Multiply by 6/5 on each side to get 30.

2. Multiply 2 on each side to get 10.

3. Add 6 on each side to get 10.

4. Divide 7 on each side to get 3.

5. Subtract 18 on each side to get 4.

6. Multiply by 3 on each side to get 27.

I gave an easy explanation, but when I say “ on each side” I mean what you do to one side you do to the other. So, for the first one to cancel it out you’d multiply 5/6 by it’s self and then multiply 5/6 on the other side of the equation or equal sign.

Hope this helps, good luck! :D

Answer:n=-2 or n=4

Step-by-step explanation:

Q is not inversible if det(Q)=0

$\left|\begin{array}{ccc}6&7&-1\\3&n&5\\9&11&n\end{array}\right| =0\\\\\\\\6(n^2-55)-3(7n+11)+9(35+n)=0\\\\n^2-2n-8=0\\\\\Delta=36=6^2\\\\n=\dfrac{2-6}{2} =-2\ or\ n=\dfrac{2+6}{2}=4\\$
